Re: TikZ to separate file (babel?) possible?

["Eric Schulte" <schulte.eric@gmail.com>]

Hi John,

In the case you describe I would export the *code* of the tikz latex
block rather than the file resulting from evaluating the block.

This is possible by adding the following header argument to the code
block which will evaluate the latex block when the export target is not
latex and will just export the code when the target is latex.

  :exports (if latexp "code" "results")
